Description

Safety fence

Technical Field

The utility model relates to a rail, concretely relates to security fence.

Background

The vertical rod in the prior art is usually directly and fixedly connected with the bottom surface, and the vertical rod is very easy to bend and damage when being collided by external force.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned technique not enough, provide a security fence, solve among the prior art pole setting and easily take place the technical problem of bending damage when receiving external force collision.

In order to achieve the above technical purpose, the technical solution of the utility model provides a security fence, include: the device comprises upright posts, a cross rod, a sliding block, a base and a spring, wherein the upper end surface of the base is provided with a sliding chute which is formed by sinking downwards, and the base is fixedly connected with the ground; the sliding block is arranged in the sliding groove and slides along the width direction of the sliding groove; the two sides of the width direction of the sliding block are respectively provided with a plurality of springs, the extension direction of each spring is consistent with the sliding direction of the sliding block, one end of each spring is fixedly connected with the sliding block, and the other end of each spring is fixedly connected with the groove wall of the sliding groove; the number of the upright posts is multiple, the upright posts are vertically arranged, and the upright posts are sequentially fixed on the upper end face of the sliding block at intervals along the length direction of the sliding block; the cross rods are arranged along the length direction of the sliding blocks and are fixedly connected with the vertical rods in sequence.

Compared with the prior art, the beneficial effects of the utility model include: when the pole setting among this safety fence received the collision, the pole setting drives the slider is relative the base slides, has reduced the probability that the pole setting received external force collision and takes place the bending, the spring plays the effect that resets, makes the pole setting can bear next impact load.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-2, the present embodiment provides a security fence, including: upright stanchion 1, cross bar 2, slider 3, base 4 and spring 5.

The upper end surface of the base 4 is provided with a sliding groove 4a formed by sinking downwards, and the base 4 is fixedly connected with the ground; the slide block 3 is arranged in the slide groove 4a, and the slide block 3 slides along the width direction of the slide groove 4 a; a plurality of springs 5 are arranged on two sides of the sliding block 3 in the width direction, the extension direction of each spring 5 is consistent with the sliding direction of the sliding block 3, one end of each spring 5 is fixedly welded with the sliding block 3, and the other end of each spring 5 is fixedly welded with the groove wall of the sliding groove 4 a; the number of the upright posts 1 is multiple, the upright posts 1 are vertically arranged, and the upright posts 1 are sequentially fixed on the upper end surface of the sliding block 3 at intervals along the length direction of the sliding block 3; the cross rods 2 are arranged along the length direction of the sliding block 3, and the cross rods 2 are sequentially and fixedly connected with the upright rods 1; when pole setting 1 among this safety fence receives the collision, pole setting 1 drives slider 3 is relative base 4 slides, has reduced pole setting 1 receives external force collision and takes place crooked probability, spring 5 plays the effect that resets, makes pole setting 1 can bear next impact load.

Preferably, a flange 4b is arranged on the outer edge of the lower end of the base 4, so that the base can be fixedly connected with the flange 4b through foundation bolts.

Preferably, the horizontal pole 2 is a plurality of, and is a plurality of horizontal pole 2 is followed the direction of height of pole setting 1 is interval arrangement in proper order to play better work that stops, every the both ends of horizontal pole 2 all are fixed with a chain 6, adjacent two pass through between the security fence the both ends fixed connection of chain 6, thereby produce when avoiding two adjacent security fences relative motion and interfere.

Preferably, the slide block 3 is provided with a plurality of through holes 3a which are sequentially arranged at intervals along the length direction of the slide block, and the axial direction of the through holes 3a is consistent with the sliding direction of the slide block 3; a plurality of guide rods 4a1 sequentially arranged at intervals along the length direction of the sliding groove 4a are arranged in the sliding groove 4a, the guide rods 4a1 are fixedly connected with the base 4, the guide rods 4a1 are in one-to-one correspondence with the through holes 3a in sliding connection, two ends of each guide rod 4a1 are sleeved with one spring 5, and the guide rods 4a1 play a good role in guiding the sliding of the sliding block 3 and the compression of the springs 5.

The working principle is as follows: when pole setting 1 among this safety fence receives the collision, pole setting 1 drives slider 3 is relative base 4 slides, has reduced pole setting 1 receives external force collision and takes place crooked probability, spring 5 plays the effect that resets, makes pole setting 5 can bear next impact load.

The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
